The association of endophytic fungi with the host plant is called a symbiotic relationship. Studies of the endophytic fungi from tea have been reported in numerous documents, but researchers still largely focus on tea endophytic fungi as they have ability to produce bioactive compounds which have numerous applications. The present work characterizes the fungal endophytic communities associated with healthy tea leaves in Yunnan Province, China. A total of 287 fungal strains were isolated from healthy leaf tissues of tea plants using a culture-dependent approach. Based on nuclear ribosomal DNA internal transcribed spacer (ITS) sequence analyses taken from the fungal cultures, strains were classified into 28 fungal genera with high similarity matches to known sequences in GenBank. The majority of genera (98.25%) belong to the phylum Ascomycota and most of the dominating fungal endophytes are from the genera Colletotrichum and Clonostachys.
